NonStop NS2400 Series Planning Guide

NOTE: For information about coexistence limits for IP and Telco CLIMs, see “IP and Telco CLIM
T CG Coexistence Limits ” (page 149).
Telco CLIM CG and Telco CLIM T (Optional)
The Telco CLuster I/O Module (Telco CLIM CG or Telco CLIM T) is a rack-mounted device that is
part of some NS2400 series system configurations and provides I/O communications using
protocols common to the Telco environment, including:
• Message Transfer Part (MTP) Level 3 User Adaptation Layer (M3UA) over IP
The Telco CLIM functions as a ServerNet Ethernet adapter and:
• Supports five Ethernet Ports that are available for SIP or M3UA processes.
• Can coexist with other types of CLIMs in the same system.
• Is configured as part of a pair for fault-tolerance.
• Connects to the maintenance switch using an embedded Ethernet port.
• Has a ground connection between the CLIM chassis and the cabinet. For detailed information
about this ground connection and the next bulleted item, ask your HP service provider to refer
to the CLuster I/O Module (CLIM) Installation and Configuration Guide
• Has a retainer for the cable management arm, which keeps the cable management arm from
moving during a seismic event.
For an illustration of the slots on a Telco CLIM, see the illustration for the commercial DL380 G6
and DL380p Gen8 Telco CLIM in “Telco CLuster I/O Module (CLIM) (Optional)” (page 29), in
which the slots locations are the same, although the power supplies differ.
For detailed information about this CLIM , including cable management and connections to other
system components, see the CLuster I/O Module (CLIM) Installation and Configuration Guide.
DAT 160 Tape Unit (Optional)
The DAT 160 tape unit is 1U high and supports two HP DAT160 internal tape drives. The tape
drives are neither dual powered nor dual ported: Each tape drive is independently powered and
has its own SAS input.

For detailed information about your system's tape unit, see the manual associated with the tape
unit (for example, the HP StorageWorks DAT SAS Tape Drives User Guide).
For information about the connections between the DAT unit and other system components ask
your HP service provider to refer to the CLuster I/O Module (CLIM) Installation and Configuration
Guide.
